概述
随着社会的进步和科技的发展，如今的游戏市场已经不仅仅局限于PS2/3、XBOX360、PC客户端等游戏。android，ios，webos等系统大规模推广之下产生了各种各样的智能手机，平板电脑等。。这就为游戏的发展注入了新的方向。这些系统各不兼容，所以，极端情况下，如果你想制作android，ios，webos这三个平台的游戏，那么，你需要部署三套代码，这样无形中就增加了制作成本。好在android有ndk，ios用的objective c也可以使用传统C++代码，webos也是如此。。这就为大家提供了一种整合的思路。我能不能只写一套核心代码，在不同的平台上只是工程文件不同就行了。目前整合的解决方案有一些，ogre，proton等。。。ogre我感觉还是有点臃肿，内存占用不是小事。。经过研究，proton算是符合我的需求了。
Proton是什么
Proton的wiki定义 http://www.rtsoft.com/wiki/doku.php?id=proton
Proton SDK (aka p+) is an open source component based C++ framework with its own touch-optimized GUI system that is optimized for GL/GLES based cross-platform app/game development. Both 2D and 3D apps (using the included but optional Irrlicht 3D engine) are supported.
features列表：http://www.rtsoft.com/wiki/doku.php?id=proton_features
其中第一条feature就是：Create 2D and 3D games that run on six platforms in C++: OSX, Win, iOS, Android, WebOS, RIM Playbook

他本身的协议是BSD的，但是他用到的一些第三方库可能是其他类型的授权
注意
proton只是个游戏的跨平台解决方案，对于其他方向可能无能为力或者没必要。比如你做一个传统的app（通讯录浏览器，美图秀秀之类），proton并不擅长做这些事情。
proton游戏下载
Tanked是一款跨平台的线上多人坦克对战游戏，这是一款免费的游戏，支持你和全世界各地的玩家在线进行对战和聊天。这款游戏支持Android、iPhone和WebOS。

代码获取
proton提供了svn下载，你可以用任意一款svn的客户端软件（我用的是TortoiseSVN）check out。地址是：svn://rtsoft.com/rtsvn/proton
下载完成后的Repository Brower截图如下
RT3DApp, RTAdTest,RTBareBones,RTBattle(需要账号，没有下载下来）,RTLooneyLadders,RTPhysics,RTSimpleApp这些是poton提供的demo
shared就是proton的核心代码了
tools是一些工具，RTPack打包用的和一些编译脚本
从这个图里（列表的右侧）就可以看到，
android，linux，osx，webos，windows，等是各平台的工程配置
source是工程的实现代码
media是资源目录。。
proton的介绍和下载就到这里了，本人没有webos，ios的平台，所以接下来我会介绍windows（vs2005），android的平台搭建教程
